SiliCycle Has Pioneered the Field of Functionalized Silica, so You Can Benefit From Our Scavenging Expertise

Challenging purifications in chemistry can be overcome creatively and elegantly.

At SiliCycle, silica gels are functionalized with various molecules featuring remarkable scavenging properties toward different metals and/or organics.

We name our metal scavengers SiliaMetS and our organic scavengers SiliaBond.

This new technology combines the benefits of century-old purification techniques, while integrating new assets that are becoming more and more critical in modern industries. New purification procedures need to be more sensitive, more efficient, quicker and greener.

It is because of today’s strive for performance yet environmental concerns that silica-based scavengers were developed : they are a strong, powerful tool with an eco-friendly twist :

  • Reduced purification steps
  • No swelling to cut cross-contaminations
  • Less solvent needed
  • Efficient precious metal recovery
